The 12th Duke of Argyll invited me to the castle of the chief of Clan Campbell 45-years ago while I was doing post-graduate work at the University of Edinburgh. Ian Campbell wrote me a note welcoming me to the castle that ended with these words: "My castle is your castle." That gracious welcome was renewed by the 13th Duke of Argyll, Torquhil Ian Campbell on April 29, 2013. I had the opportunity of interviewing the Duke of Argyll at Inveraray Castle. He represents Pernod Ricard distillers and promotes Scotch whiskies. He is married to Eleanor Cadbury of the Cadbury chocolate family. They have three children. You can visit the Duke of Argyll at the Inveraray Castle's website.
